I want to run this game at 60fps without vsync, but at least it should not run at 30fps with vsync on.

From what I've read, the only way to get more than 30 FPS is to disable v-sync. But it mentions using a 3rd-party program called "MSI Afterburner."

Sadly no but you can force Vsync in your GPU control panel though and you will not get that 30 FPS cap.

You need to disable VSync from the visual options ingame and enable it in your GPU software. You can go even one step further and force AA and AF right there for better results(just create a profile for your game if the software didn't already created one for you).

But if you already did this and what you get is screen tearing all the time, you should download a 3rd-party software to fix this. I use an AMD graphics card, and if you do as well then I suggest to download and install RadeonPro.

Disable the VSync settings in your GPU software for Dead Space(in case you enabled them there). Then Open RadeonPro, create a profile for Dead Space, then go to the Tweaks tab and enable VSync there. I haven't tested any other configurations, but so far this has fixed the tearing to me, so I'm happy and I don't really need to test anything else:

VSync Control = Always on (Double VSync)
Display refresh rate = 60
Tripple-buffering = On
Lock frame rate up to monitor's refresh rate = On

The last one was checked in automatically when I selected the first, but since I have no problem so far I left it as it. But you can always test multiple setups until you find the one you prefer :).

TIP: Go to the app settings(third button in the bar from left to right) and in the FPS section hide it, otherwise it will pop up as soon as you open the game.

When you finish you can close it and it will hide in the system tray. Then you can play this game enjoying 60 FPS without problems.

the above tip works very well, i noticed that locking the framerate to 58 instead of 60 causes less lag and if anyone is using an nvidia card nvidia inspector works for this
